Thread: Drill Doctor transformer

I am not able to help you with your question but welcome to the forum.

If you look at the spec's for the DRILL DOCTOR' s motor , you will see the watts/ amps , that the motor requires, you can the buy the step down transformer, that will suit , I would buy a unit that gives at least 20% higher output, this will prevent overloading, of the transformer.

Please realise that buying this way , may mean that the all up cost could be higher than sourcing in AUS, also if you have a problem with the unit , then repairs my cost more, and any warranty claims could be interesting.

The difference in frequency may be a problem as well. Not sure what speed the DD runs at but presume it needs to be reasonably high. The drop to 50 Hz may make it work less efficiently than desired. Just something else to consider

G'day fellas,
Sorry for the delay in answering.
Thanks for the welcome and the input.
As far as the varying frequency is concerned, I don't think that this will make a big difference. However I will double-check that tomorrow.
As far as the cost goes, it should work out a lot cheaper. I realise of course it would give extra complications from a warranty claims, but I'm simply not going to worry about any warranty. If the thing blows up, I'll simply wear it.
I have bought a couple of things overseas before, but these were the things that were not sold in Australia. This is the first time I'm buying something because of price.
I don't mind paying a fair price, but I don't like being ripped off.
These Drill Doctors are very popular, and they sell them all round the world. I believe that they've made 3 million of them. So they would do production runs for the varying voltages around the world. Therefore they shouldn't be much more expensive than the US version.
Here in Australia, the price seems to vary from about $320-$380. In the US the price is $135. A ludicrous difference.
I'll pay the US price plus shipping plus a stepdown transformer here in Australia, and still be well in front.
At a later date, I may be going to the US, and while over there I'll need to buy some basic electrical tools to do some work (e.g. battery drill). So if I want to bring them back with me I'll have a transformer to power them.
Cheers John

Hi, the Drill Doctor draws 1.75 A @ 110V = about 200W. Seeing as you may get some other 110V tools, and it's best to get a unit that can deliver a bit more than what the Doc draws while running, I'd suggest that you get a 250w transformer minimum, preferably 500W if you want to run more than just the Doc.

There are plenty of Au-supplied 240-110V transformers via eBay.

I totally agree that we are getting done over with the extortionate prices that are being charged in Au for electrical goods, machine tools and the rest. Luckily, the Internet now allows us to have choice and source goods at reasonable prices.
